:DRAFT EVENER.

Application mean-April s,

rThis invention relates'to improvements in draft equalize'rs and more particularly to device of this Lcharacter adapted foru'se by three or more draft'aniinals, although it 1s capable of other uses. vOne object is to provide a draft equalizer that is positive and efficient in operation and that .can be readily appliedto vehicle tongues of lordinary construction. V 'i `Withthe foregoing and other objects in' view the invention' consists in` the combination and arrangement of parts tobe hereinafter fully described, particularly pointed out in the claims and-illustrated. in 'the accompanying drawings which form a part of this application and in which n Fig. 1 is a top plan view of `the drafty` equalizer applied tofar vehicle tongue. Fig. 2 is a view of Fig. 1 in rear elevation. Figs. 3 and 4 arel enlarged cross sectional views taken, respectively,y on li'nesg'fand fl-tof Fig. 1. y' F ig. o is a longitudinal `sectional vview through the main barj'of the invention and is taken on line 5-5 of l. l

Like reference characters denote corresponding parts throughout. the several views.

`Where the power or pull is unequally di- E vided upon the sides of theI vehicle pole it is the purpose 'of the present invention to equalize the draft. This is accomplishedby the novel arrangement and assembly of means for receiving and distributing the stress on the several' members associated with the pole and comprising a splinter bar that extends across the pole and is connected thereto by mechanism arranged upon each side of and across the pole.

The reference numeral 1 denotes the vehicle pole of common formation. Abolt 2 extending through the vehicle pole secures thereto one end of the hammer strap 8, the body of said strap being raised relative yto said pole and extendinglongitudinally thereof, the forward end thereof being spaced above the pole and supported upon the bushing L1 of a bolt that likewise extends;V through the pole. Secured to the hammer strap 3 by a bolt 6 is one end of an angular or L-shaped lever 7 that extends out laterally from said strap and is further secured thereto and to the pole by the brace strap 8. The outer and shorter end of the lever 7 is pivotally received in one bifurcated end of an angle bar 9 and secured therein by bolt 10.

The angle bar 9 extends inwardly from 1927. Serial No. 182,039.

the shorter end of the lever 7 across the pole 1 and beneath 'the forward end of the hammer strap 3 and is fulcrunied upon a bolt 1.1 that connects it tothe splinter bar 12,l the shorter end of said bar 9v being connected by bolt 131130 `the straight bar 14@ that extends inwardly to the. pole 1 and is connected by bolt 15 to the triangular plates 16, 17 that engage withthehorizontal faces of the bar 1st and connect saidbar to the splinter bar 12 to which said plates are secured by the bolt 18, a brace strap 19 extending longitudinally o'f the pole 1 but spaced thereabove also connecting the bolts 18 and 15.

yConnecting the apex of each triangular plate 16, 17 by means of bolt 2O are'the parallel spacedl straps 21, 22 that are'also connected by bolt 23 to one end of the right angled lever 24 that is fulcrumed upon'a bolt 25 to which a pair of parallel spacer straps 26,l 27 are secured-that are also connected byv bolt 11 to the splinter bar. Likewise secured totlie'bolt 25' are the spacer straps 28, 29 also connected by bolts 30 to the splinter bar, the straps 28, 29 taken withstraps V26, 27 and splinter barY 12A forming a triangle to the apex of which the lever 24 is fulcrumed.

' Referring again to the lever 24 'a bolt 31 passing through the end thereof remote from f bolt 23 engages the Abifurcated end of the take-up bar 32'the opposite end of which is threaded and adjustably connected to the yoke 33 that is connected' by bolt 34e-to `the lever 7, said take-up'bar and yoke extending .from one side of the tongue 1 to the other.

A doubletree (not shown) is secured to the shorter end of the splinter bar and a singletree V(not shown) to the longer end.

The forward pull of the draft animals e sricles,4 PATENT orifice. A

upon the splinter bar would be transmitted from the; through bolts 18, 11, 30. A straight line connecting the bolts 25, 11 would pass through the bolt 31 and pass to the right of the bolt 13. Should the pull of the draft animals at the doubletree on the shorter or right end of the splinter bar be exeessive this pullV would be equalized by the strain passing from bolt 18 through bolt 15, then to the left of the pole through straight bar 14 and it would be applied to angle bar 9 to the left of its fulcrum point 11 thereby tending to bring forward the longer side of this bar, upon the right side of the pole, thus pulling forward upon the lever 7 to which the yoke 33 is pivoted at 34. Through yoke 33 and take-up b-ar 32 the strain would be transmitted to lever 24 through bolt 31 thus tilting this lever upon its fulcrum 25 and bringing forward bolt 23 and straps 21, 22 which would transmit through`bolt20 to plates' v16, 17 to bolt 15. In the presentV construction and assembly'the splinter bar is so disposed relative to the pole 1L that one third of the length of the splinter bar is normally upon the right hand side of the pole 1 and two'thirds of the splinter -bar upon the left side thereof. Should the pull of the/draftV animals vcause a slide draft which would move the splinter bar to thel left relatively to the pole it would be the V straight bar 141 and straps 21, 22 to plates 16,

purpose of the equalizing mechanism to automatically re-pos1t1on these members.

In the present relative positionsfofthe splinter bar and pole a straight line connecting the bolts 34, A10 should be more thanI twice the distance from the pole of a straight line connecting the bolts 25, 31. This will cause any pull that would exert a side draft to the left to correct itself as the leverage exerted through the angle bar 9 and members 32, 33 moving forward,

upon vthe right side' of the tongue would cause sucient pressure upon the splinter bar through bolt 11 and connections and upon s connected elements of the device.

Whatisclaimed is :f- 1. In a draft equalizer, a splinter bar extending transversely of the vehicle draft pole, an angle bar pivotally connected to the splinter bar upon one side ofthel pole `one kend of said angle vbarV and the pole upon the side thereof remote from the pivotal' point of said angle bar, spacer straps connected to the splinter bar, a right angled lever fulerum to said spacer straps, adjustable yoke and take-up connection between one end of said right angled lever and L-shaped bar, spaced triangular plates pivotally secured to said splinter bar, straps connecting saidA triangular plates and right angled lever, and connection between the said angular bar and said triangular plates. y

2."In a draft equalizer, a splinter bar extending transversely of the vehicle draft pole, an angle bar pivotally connected to the splinter bar upon one side of the pole and extending from said' pivotal point to opposite sides of the splinter bar and of the pole, an L-shaped bar pivotally connectingy one end of said'angle bar and the pole upon the side thereof remote from the pivotal point-of said angle bar, spacer straps con# nected to thel splinter-bar upon the side of the pole opposite to said L-shaped bar, a

vright angled lever fulorumed to said spacer straps, adjustable yokel and take'up connec-` tion between; one end of said right angled lever and L-shaped bar and'extending acrossy they pole, spaced triangular plates pivotally secured to said splinter bar, straps connecting said triangular plates and right angled lever and'disposed wholly upon the side of the pole opposite to 'said Llshaped lever, and connection. between said angular bar and triangular plate'supon the same side of said pole as said'last named straps.

e In testimony' that I vclaim the foregoing as my own I, have hereto affixed my signature.
